Title:
SWITCH AND DEVICE USING THE SWITCH
Document Type and Number:
WIPO Patent Application WO/2005/076301
Kind Code:
A1
Abstract:
There is provided a switch having a new function for protection from excessive current. The switch includes a conductive movable member (9) and at least two terminals (1, 2, 3). By mechanically moving the movable member (9), the switch can be set to a state that the movable member (9) is simultaneously brought into contact with the two terminals (1, 2) and to a state that the movable member (9) is apart from one (1) of the two terminals (1, 2). At least one (2) of the two terminals (1, 2) is separated into a conductive contact unit (2a) which is brought into contact with the movable member (9) and a conductive connection unit (2c) which is electrically connected to an external element (not depicted). A PTC member (2b) is arranged so as to be sandwiched between the contact unit (2a) and the connection unit (2c). The PTC member (2b) may be a PTC element having a PTC material layer and a pair of conductive material layers arranged on the opposing surfaces.
